Mars Odyssey — spacecraft, shown live in Cosmoscope, a real-time 3D map of the universe.
The longest-working spacecraft at Mars: Odyssey mapped the planet’s ice and minerals and still relays signals from the surface decades on.
Cosmoscope draws Mars Odyssey on its real trajectory, from mission ephemeris rather than an artist's impression. Open the live 3D view to see where Mars Odyssey is right now, how far it has travelled from the Sun, and how long its radio signal takes to reach Earth. Scrub the timeline to replay the route that took it there.
